.To wi zzz/1,0m t may concern,.-

Be it known that I, CHARLES MARIE JULES PETIET, a citizen of theRepublic of France, residing at Villeneuve-la-Garenne, Seine, France,have invented Improvements in Means for Supporting and Driving theWheels of Motor Road-Vehicles, of which the following is aspecification.

This invention has for its main object to provide an im roved member,which for convenience I will call an axle, for supporting thedriving-wheel shaft and driving-wheels of motor road-vehicles. This axleis preferably of wrought-steel and is made in one piece and of anydesired form in cross-section. Its journals receive the inclinationwhich is suit able, according to the inclination to be given' to thewheels. The accompanying drawings show a typical form of the saidaxle-carrier and illustrate the manner in which the wheels turn on thebearings thereof and how they are driven by the transmission-shafts ordriving-axles.

Figure l is 4a part vertical section of the axle-carrier and mechanismfor transmitting the motion to the wheels, only one of which is shown. Fig. 2 is a longitudinal section, on a larger scale, through one of thebearings. Fig. 3 is a section on M M of Fig. 2, and Fig. 4 is a sectionon N N of Fig. 2.

The axle A, made in one piece of wroughtsteel` of any desired section,carries the journals B, which have a certain inclination to giveinclination to the wheels. The hub C of each wheel is mounted withslightfriction on the journals B,`a bronze sleeve a being preferably fittedbetween the hub and the journal. If desired, ball-bearings may beinterposed between the hubs of the wheels and their journals. Ineithercase the wheels are themselves carried by the axle and run looselyon these journals.

An ordinary or suitable dierential gear D, driven by the motor throughany suitable flexible transmission, is fixed on the middle of the axleA. The axles of the two drivin pinions E have squared holes l), in whicht with slight friction the4 ends c of two rigid shafts F,these endsbeing likewise squared, but being slightly olive-shaped. These twoshafts, connected as explained to the drivingpinions of the.differential gear, transmit the motion to thewheels R through their hubsC.

The internal diameter of the holes d in the journals of the axle A issufficient to allow of the parts E of the driving-.shaft to beintroduced through the outer ends ofthe journals and their extremitiesto be inserted into the squared hole b in the hub of the correspondingpinion. At its other end the drivingshaft F carries a disk or plate e,provided peu ripherally with teeth in the form of segments f, adapted toengage in gaps of the same shape between the teeth j", formed with orunited to a box G, forming a prolongation of the hub C of the wheel. Inthis Way the rotation of the vshaft F is transmitted to the hub of thewheel in an absolutely certain manner.

The wheel is held on its journall as shown in detail in Figs. 2 and 4.On the side toward the center the hub of the wheel carries a 'washer orcollar g, which bears against another collar i, which in turn bearsagainst a flange or face H of the axle, a ball-bearing h being fittedbetween g and fi. At the outer side a metal ring lc is provided, thishavin' a conical face to bear against a corresponding yshaped portionofthe hub. This ring k is cut or shaped so as to present two flats or-bearing-faces m, corresponding to two flats or bearing-faces formed atthe ends of a diameter ofthe threaded end I ofthe journal of the axle,as seen in Fig. 4. In this way the ring lc is prevented from turning onthe journal. A nut n is screwed on the end of the journal and bearsagainst the rear face of the ring k. Another ring o with a flat. orbearing face is fitted behind the nut, and screws pare passed throughthe ring o and into the nut n and prevent the said nut from becomingunscrewed. The wheel being thus properly mounted on the journal, theshaft F is passed through the hole in the journal, care being taken thatthe segmentsfof the plate ordisk pass into the gaps between the teeth fin the box of the hub, as before explained.

It will be observed that the disk e of thev axle has a projection or niple 1 on its outer face, around which is fitte a coiled spring r.

K is a cap screwed into the box G to close the saine and likewiseprovided centrally with a nip le s, over which the spring r fits. Theend ol the shaft F has thus a resilient bearing against the cap of thejournal.

What I claim is-- The combination of an axle A made in a single ieee, adiferential gearing fixed on said ax e, transmission-shafts F connectedto the drivin pinions of the differential by means of o ive-shapedsquared heads engaging in squared holes in the hubs of said pin'- ions,the hubs of the Wheels being journaled on the ends of the axles, ringsarranged nonrotatively on the ends oi the axles retaining said hubs inplace, a box forming a'prolon ation of the hub ot'eaeh Wheel and provied With aps, teeth on the ends ot the transmission-s afts en agin insaid gaps to transmit the rotation o the s aft to the wheel, a screwoapclosing the end of eaeh of said boxes, and a spring interposed betweenthe end of each shaft and said gap to form a resilient bearing orabutment. l

In Witness whereof l have hereunto signed my name in the presence of twosubscribing Witnesses.
